NeRF(Neural Radiance Field)即神经辐射场 要解决的主要问题:从图像中得到三维模型 什么是三维模型? 抽象来说,三维模型主要分为形状(shape)和外观(appearance),外观又可以粗略分为材质(material)和光照(lighting),在我们得到这些基础信息后,我们只需要经过一定的渲染算法,就能够得到图像。这个从模型到图像的
总而言之,Radiance Field描述了在三维空间中每个点的辐射度(radiance),这代表了在该点上的光照强度和颜色。通过学习辐射场,可以生成逼真的图像,包括场景中的各种光照和反射效果。 体素密度 在三维图形学和计算机视觉中,体素密度 $\sigma(x)$通常用来表示体积数据中每个体素(三维像素)的密度或吸收率。这个密度函数 $...
Neural radiance fields (NeRFs) use deep learning to turn 2D images of objects or scenes into detailed 3D representations byencodingthe entire scene into an artificialneural network. The model then predicts the light and color intensity, orradiance, at any point in the 2D representations of a 3D...
NeRF全称为Neural Radiance Fields(神经辐射场),是一项利用多目图像重建三维场景的技术。该项目的作者来自于加州大学伯克利分校,Google研究院,以及加州大学圣地亚哥分校。NeRF使用一组多目图作为输入,通过优化一个潜在连续的体素场景方程来得到一个完整的三维场景。该方法使用一个全连接深度网络来表示场景,使用的输入是一个...
